Sun and thermal energy: Europe’s precious energy sources for efficient industries and buildings | Sustainable Places 2019, Cagliari, 05-07 June 2019
Keywords: solar, thermal, renewables, energy efficient buildings, industry, heat pumps
In this workshop, we discussed the progress of five Horizon 2020 projects – HYCOOL, SHIP2FAIR, THERMOSS, SUNHORIZON and HYBUILD – all implementing solar thermal and renewable technologies for buildings and for the industrial sector. The discussion offered opportunities to identify and benchmark key challenges being faced by the projects, both technical and non-technical, and allowed to identify cooperation opportunities.
Key innovative aspects:
The main goal and innovative aspect of SHIP2FAIR is to foster the integration of solar heat in industrial processes from the agro–food sector.
SunHorizon aims to develop heat pump solutions that will act properly coupled with advanced solar panels providing heating and cooling both for residential and tertiary buildings.
THERMOSS ensures an efficient match between supply and demand of energy through real- time management of thermal energy and by retrofitting through advanced heating and cooling technologies, leading to up to 30% savings in energy consumption.
HYCOOL’s mission is increasing the use of solar heat in industry processes, by coupling of a new Fresnel CSP Solar thermal collectors (FCSP) with specially build Hybrid Heat Pumps.
HYBUILD combines a compact sorption storage, a high-density latent storage, and an efficient electric storage in residential buildings.
The 5 projects discussed the following common horizontal issues :
Highest technological challenges faced by the projects
How digitalization and monitoring data can facilitate the promotion of the technologies of the projects
How to increase social acceptance of projects’ technologies, and main non-technological barriers
Key measures to achieve cost-reduction of projects’ technologies

In the face of an ever more extreme climate the world is calling urgently for answers to questions of how people can stay not only comfortable, but also thermally safe and healthy in a warming world. Current and future temperature trends and events threaten not only buildings, settlements and cities but also the temporary settlements built to cope them such as transient populations.
CATE 2019 gathered leading international figures from many fields to discuss crucial questions and ways forward on how to best provide Comfort at the Extremes.
The Eurotherm seminar #112 – organised at the University of Lleida – did bring together researchers and practitioners from academia and industry, who are working in the rapidly-expanding field of thermal energy storage.
The most recent trends in areas such as novel storage materials, advanced storage concepts and configurations, thermal energy storage for renewable energy systems, and thermal energy storage in buildings were presented. This conference provided a forum for discussion among academics, researchers, and professionals who work in the field of thermal energy storage.
The event gathered more than 130 attendees.
At the European exhibition corner, some participants were interested in receiving more details regarding the two systems developed within HYBUILD. HYBUILD partners presented some intermediate technical outcomes of the project by means of either oral presentation or posters. Useful feedback was received from experts in the topic.

The role of Eurac Research in Hybuild
Eurac Research is the main partner in charge of the models and simulations for the Mediterranean and Continental Hybuild energy systems and buildings. Energy models of demo and reference buildings, heating and cooling systems and hybrid storages will be developed and simulated for: i) evaluating the proof of concept through the KPIs identified in the project, ii) computing the LCA and LCC analysis and iii) testing the developed control strategies. Once the systems will be installed in the demo-cases, the models developed by Eurac Research will be validated through measurements data to have a benchmark for the performance of the running systems. Both Mediterranean and Continental concepts will be also simulated in identified reference buildings overall Europe in order to demonstrate the replicability of the Hybuild systems.

HYBUILD is co-organising a a workshop at Sustainable Places 2019, 5-7 June, Cagliari (Italy).
The workshop is entitled Sun and ambient heat: Europe’s precious energy sources for efficient industries and buildings. It will present the technological systems of five H2020 projects: HYCOOL, SHIP2FAIR, THERMOSS, SUNHORIZON and HYBUILD; each implementing renewable energy solutions to conserve energy and improve thermal comfort for both the residential and industrial sectors. The workshop is also supported by EHPA (European Heat Pumps Association) and ESTTP (European Solar Thermal Technology Panel).
Hybrid sorption-compression systems are gaining interest for heating/cooling/ refrigeration purposes in different applications, since they allow exploiting the benefits of both technologies and a better utilization of renewable sources. However, design of such components is still difficult, due to the intrinsic complexity of the systems and the lack of reliable models. In particular, the combination of adsorption-compression cascade unit has not been widely explored yet and there are no simulations or sizing tools reported in the literature. In this context, the present paper describes a model of a hybrid adsorption-compression system, realised in Modelica language using the commercial software Dymola. The models of the main components of the sorption and vapour compression unit are described in details and their validation presented. In addition, the integrated model is used for proving the feasibility of the system under dynamic realistic conditions and an example of the technical sizing that the model is able to accomplish is given.

CSEM in a nutshell
CSEM is a private, non-profit research and technology organisation created in 1984. Its mission is to develop and transfer microtechnologies to the industrial sector – in Switzerland, as a priority – in order to reinforce its competitive advantage. It does so through cooperation agreements with established companies as well as by encouraging the creation of start-ups (43 so far, leading to the creation of 400 jobs). It holds 203 patent families and filed 26 new patents last year. CSEM has about 440 employees and achieves an annual turnover of 83 million CHF.
CSEM has its headquarters in Neuchâtel, in the heart of watchmaking region and four regional centers across Switzerland.
Its research is organised in five technology programmes: microsystems, surface engineering, systems, ultra-low-power integrated systems, and PV-center and energy management. Since 2013 CSEM PV-center is the national competence center for photovoltaics. Within this center, a 14-strong team develops solutions to build and manage an efficient, sustainable- energy world based on distributed renewable power generation. It brings together the skills to engineer this new world: power engineering, power electronics, signal processing, machine learning, optimization and control, and systems engineering. It provides services and technologies in three main areas: energy data, decentralized control, and electricity storage in supercapacitors and batteries. Applications of CSEM technologies have already been demonstrated on inverters, in direct current (DC) microgrids, and in energy management systems for residential and commercial buildings. We work with component vendors, system integrators, and utilities to turn these technologies into successful products.
CSEM role in HYBUILD
In the framework of the HYBUILD project, CSEM is developing an integrated and certified DC microgrid. This DC microgrid is meant to interface an external distribution grid, a local renewable energy source, a heat pump and a storage system with the objectives of optimizing the system efficiency and compactness. This work includes the selection of optimal components and its integration in compliance with the norm EN/IEC 61439. Moreover, a low-level controller, as well as its communication architecture, will be developed guaranteeing a stable operation of the DC microgrid while offering control flexibilities to a higher level optimizer.
